Ungakhetha njani phakathi kweempompo ezithe tye nezithe nkqo kunye neenkqubo zamanzi omlilo zepayipi？
Impompo Yamanzi OmliloIzinto ekufuneka ziqwalaselwe
Ipompo ye-centrifugal efanelekileyo ekusetyenzisweni kwamanzi omlilo kufuneka ibe negophe lokusebenza elithe tyaba. Ipompo enjalo inomlinganiselo wemfuno enye enkulu yomlilo omkhulu kwisityalo. Oku kudla ngokuthetha ngomlilo omkhulu kwiyunithi enkulu yesityalo. Oku kuchazwa ngumthamo olinganisiweyo kunye nentloko elinganisiweyo yeseti yepompo. Ukongeza, ipompo yamanzi omlilo kufuneka ibonise amandla okuhamba kwamanzi angaphezu kwe-150% yomthamo wayo olinganisiweyo kunye ne-65% yentloko yayo elinganisiweyo (uxinzelelo lokukhupha). Ngokwesiqhelo, iipompo zamanzi omlilo ezikhethiweyo zidlula amaxabiso akhankanyiweyo ngaphambili. Kukho iipompo zamanzi omlilo ezininzi ezikhethwe ngokufanelekileyo ezineegophe ezithe tyaba ezinokubonelela ngaphezulu kwe-180% (okanye i-200%) yomthamo olinganisiweyo entloko kunye nangaphezulu kwe-70% yentloko iyonke elinganisiweyo.
Kufuneka kubonelelwe ngeetanki zamanzi omlilo ezimbini ukuya kwezine apho kukho umthombo ophambili wamanzi omlilo. Umthetho ofanayo uyasebenza kwiimpompo. Kufuneka kubonelelwe ngeempompo zamanzi omlilo ezimbini ukuya kwezine. Ilungiselelo eliqhelekileyo leli:
● iimpompo ezimbini zamanzi omlilo eziqhutywa yinjini yombane (enye isebenza kwaye enye ikwimeko yokulinda)
● iimpompo zamanzi omlilo ezimbini eziqhutywa yinjini yedizili (enye isebenza kwaye enye ikwimeko yokulinda)
Omnye umngeni kukuba iimpompo zamanzi omlilo zisenokungasebenzi ixesha elide. Nangona kunjalo, ngexesha lomlilo, nganye kufuneka iqaliswe ngoko nangoko kwaye iqhubeke nokusebenza de umlilo ucime. Ke ngoko, kufuneka amalungiselelo athile, kwaye impompo nganye kufuneka ivavanywe rhoqo ukuqinisekisa ukuqala ngokukhawuleza kunye nokusebenza okuthembekileyo.
Iimpompo ezithe nkqo vs. Iimpompo ezithe nkqo
Iimpompo ze-centrifugal ezithe tye zezona zikhethwa kakhulu ngabaqhubi abaninzi kwimpompo yamanzi omlilo. Esinye sezizathu zoku kukudakumba okuphezulu kunye nolwakhiwo olusesichengeni lweempompo ezinkulu ezithe tye. Nangona kunjalo, iimpompo ezithe tye, ngakumbi iimpompo zohlobo lwe-turbine ezithe tye, ngamanye amaxesha zisetyenziswa njengeempompo zamanzi omlilo. Kwimeko apho unikezelo lwamanzi luphantsi komgca ophakathi we-discharge flange, kwaye uxinzelelo alwanelanga ukuhambisa amanzi kwimpompo yamanzi omlilo, iseti yempompo yohlobo lwe-turbine ethe tye ingasetyenziswa. Oku kusebenza ngokukodwa xa amanzi avela emachibini, emachibini, emigodini, okanye elwandle esetyenziswa njengamanzi omlilo (njengomthombo oyintloko okanye njengenkxaso).
Kwiimpompo ezithe nkqo, ukuntywiliselwa kwezitya zempompo yeyona ndlela ifanelekileyo yokusebenza ngokuthembekileyo kwempompo yamanzi omlilo. Icala lokufunxa lempompo ethe nkqo kufuneka libekwe nzulu emanzini, kwaye ukuntywiliselwa kwe-impeller yesibini ukusuka ezantsi kwesitya sempompo kufuneka kube ngaphezulu kweemitha ezi-3 xa impompo isebenza ngesantya sayo esiphezulu sokuhamba. Ngokucacileyo, olu lulungiselelo olucwangcisiweyo, kwaye iinkcukacha zokugqibela kunye nokuntywiliselwa kufuneka zichazwe kwimeko nganye, emva kokubonisana nomenzi wempompo, abasemagunyeni bomlilo basekuhlaleni kunye nabanye abachaphazelekayo.
Kubekho iimeko ezininzi zokungcangcazela okuphezulu kwiimpompo ezinkulu zamanzi omlilo ezithe nkqo. Ke ngoko, izifundo ezinobuchule kunye nokuqinisekiswa kuyafuneka. Oku kufanele kwenziwe kuzo zonke iinkalo zokuziphatha okuguquguqukayo.
